Alison didn't know she'd be forever sixteen. Immortalised in death, she's wanted by the demons of Hell who would do anything - including hurting her, and eradicating her soul - to get what they want. Only thing is, she doesn't know why. It might have something to do with her mysterious death and it seems her recently-dead companion, the enigmatic Matthew Harland, might know something about it. Alison is determined to find out exactly what. It could just help her escape the netherworld.
